Application filed February 15, 1916.

T 0 all whom it may concern:

Be it known that I, OLE O. S'roRLn, a citizen of the United States, residing at the city of Tacoma, in the county of Pierce and State of lVashington, have invented certain new and useful Improvements in Explosive-Engine Governors, of which the following is a specification.

My invention pertains to governors for explosive engines. The objects of my invention are, first, to provide a governor that will secure uniform speed in an explosive engine; second, to produce a governor that works noiselessly and with minimum fric tion, and third, to produce a governor that is simple in construction, durable and per foot in operation.

I attain these objects by means of the mechanism illustrated in the accompanying drawing, in Which Figure 1 is a side view of the central part of an explosive engine fly wheel with my newly invented governing mechanism mounted thereon. Fig. 2 is sectional view of the same on line 2 2. Fig. 3 is a View of the flexible governing finger looking upward toward Fig. 1. Fig. 4 is a top view of the a11- nular eccentric and centrifugal weight of the governing mechanism.

Similar characters refer to similar parts of the several views.

My newly invented governor is represented as mounted on the hub A of the fiy wheel B. My invention comprises an annular eccentric C, a centrifugal weight D attached 7 thereto, an anchor bolt E and an adjustable spring F to control the centrifugal force of said weight D. The spring F at its outer end actuates against the threaded nut G of the bolt E, the head H of said bolt being anchored in a slot of the guide plate I fixed on the fly wheel B, for instance, by the nutted bolts P. The weight D is slidable in a guide-way of the plate I as indicated in Figs. 1 and a; and the weight has the eccentric C integrally, or otherwise, attached thereto so as to be moved radially with the weight. The inner end of the spring F rests on a seat J within the weight D and thus controls the centrifugal force thereof.

It will be observed the side of the hub A is cut away at at opposite the weight D to permit the annular eccentric C to be drawn off the hub center by the centrifugal pull of weight D, thus obtaining a centrifugal con trolling device with which to operate the Specification of Letters Patent.

pivotally mounted on the stud N. By means of the hair-pin spring 0 thus confined by the lugs mm and pp a flexible connection is obtained between lever M and trip finger P.

The lever arm Q3, pivotally mounted on the stud R, is designed to operate the exhaust valve of the engine. This lever arm Q is actuated by the cam S which is driven by the gears T and U at one-half of the speed of the engine. The control of the engines speed is obtained by interrupting the action of the lever arm. Q and holding the exhaust valve open. 'The'suction of the intake stroke of the piston is thus relieved and the automatic intake valve does not open. This is accomplished by the engagement of the point of the trip finger P with the adjustable lug V attached to the lever arm Q.

It is to be observed that at the time the lever arm Q, is lifted by the cam S, the centrifugal weight D will be on the opposite side of the shaft to that shown, and, if the speed of the engine is excessive, the trip finger P will be sprung over so as to engage the lug V of the arm Q and thus prevent the engine exhaust valve being closed. The beveled end of the trip finger P and of the lug V is such that the strength of the hairpin spring Owill not be suflicient to disengage them. The lug V, however, is so adjusted that at each revolution of the cam S it is lifted clear of the trip finger P for an instant, and as soon as the engines speed has been reduced to normal the trip finger P will spring back to its normal position during this interval. The lever Q will then be released, allowing the engine to resume its regular operation.

It will be observed that mechanism of my invention is adaptable to any form of explosive engines, the parts being easily made of such sizes and proportions as the case may require. The construction of the several parts is simple and economical; the mechanism will work with minimum friction, will be perfect and durable in operation, and will secure a uniform speed in the-engine.

Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. In an engine governor, an eccentric and a centrifugal weight for moving the eccentric radially, a trip finger adapted to be thrown into locking engagement with a valve lever of the engine, an arm operatively connected with the eccentric and with the trip lever, and a spring connection between the arm and trip lever, said arm and trip lever being actuated by radial movement of the eccentric imparted from the centrifugal weight. v

2. In an explosive engine governor, a grooved annular eccentric, having a centrifugal weight attached to its outer rim, said centrifugal weight controlled by a fixed guide and an adjustable spring, a segmental slide in the groove of said annular eccentrio, said segmental slide pivotally connected with a short lever arm in combination with a trip fingerv and a hair-pin spring, substantially as shown and described.

3. In an explosive engine, governor, a grooved annular eccentric having a centrifugal weight attached to its outer rim, said centrifugal weight controlled by a fixed guide and an adjustable spring, a segmental slide in the groove of said annular eccentric, said segmental slide connected with a short lever arm pivotally mounted in combination with a trip finger, a cam actuated Valve lever arm provided with a trip lever engaging lug, said trip finger being flexibly controlled by a double acting hair-pin spring to govern its engagement with the adjustable lug of the cam actuated valve lever arm of the engine, substantiallyas described and shown.-

4.- In an explosive engine governor, a grooved annular eccentric having a centrifugal Weight attached to its outer rim, said centrifugal weight controlled by a fixed guide and an adjustable spring, a segmental slide in the groove of said annular eccentric, sa1d segmental slide connected wlth a short lever arm pivotally mounted 1n combinatlon with a trip finger, the lever arm and the tripfinger each having lugs, and a hair-pin spring held between the projecting lugs of said lever arm. and trip finger so that when one is drawn sidewise in either direction it will compress the spring, and when released the spring willthrow the other into place, as

described and shown. 7

In testimony whereof I afiix my signature in the presence of two witnesses.-
